The freshwater aquarium is lots of fun, but I want to step a little outside of my comfort zone with the next "build."

Here's what I got:

Tank
20 gallon glass aquarium (24 1/4" x 12 1/2" x 16 3/4")

Lighting
CustomSeaLife 24" 65w x2 power compact (One white bulb, one blue) Not sure of the exact model. Can't find too much info on it. Since I know how to wire up LEDs, the moon lights are going to be the same custom deal I did on the freshwater aquarium. See link above for that...

Filtration
Eheim Professional II 2028 with custom PVC plumbing - No powerhead at first because I anticipate that the Eheim (having a variable flow rate) will move enough water to suffice).

Heater
Rena Cal Top Light Excel 100w

Substrate
Quikrete Premium Play Sand

Rock
Maybe Totoka. Still not 100% on my source at this point.

Fish/CUC
No idea, yet. Suggestions?

The Build
Well, I picked up the tank, some HOB filter, some heater, test kits, hydrometers, specimen container, lights, etc... off of craigslist for $40. I think I got a pretty darn good deal...

Today, I filled the tank to check for leaks. Seems fine. I then cleaned the glass. As of right now, I am about to go put the last layer of paint on the rear panel. Krylon Fusion blue. Looks awesome. I can't wait to see the sand and blue contrast with the lights. It's gonna be beautiful.

If you know me, you know that I LOVE posting tons of pictures. Unfortunately, I will have to wait until tomorrow when I have better lights to do so. As for now, send me some tank occupants suggestions!

Good on you to venture into the Marine world. It's come a long ways since I did it years ago.

There are some attractive damselfish that get overlooked, colorful wrasses that stay small and a few pigmy angelfish that would work in this size tank. Plus all the shrimp and the like I never got into.

Very detailed post the way.

I'm sure Cliff will weigh in to help you out.

Good luck and have fun.

If you are planning to add corals, I would suggest upgrading the lighting

As for fish suggestions here are a few to consider: Oscellaris Clownfish (Amphiprion ocellaris), Purple Firefish (Nemateleotris decora), Longspine Cardinalfish (Zoramia leptacantha), and most of the gobys like the Dracula Goby (Stonogobiops dracula) are are indivdual options that could work in a tank you size. Those would be about the best options (IMO) for a tank your size

As for your CUC, snails like Spiny Star Astraea (Astraea phoebia), Nassarius Snail (Nassarius sp.) and Margarita Snail (Margarites pupillus) are all options that should work as well

I would also suggest a refactormeter instead of a hydrometer. It is not uncommon to find that hydrometers can be out by as much is 0.003 which can cause swings in your pH and other paramteres. Refactormeters are much more accurate

What were you planning to run in the filter ?

I think in a few years I will be trying this myself so I look forward to how this progresses.

Yeah, I have been itching to get this going for some time now! The progress won't be in too big of a hurry, though.

I will be checking out the fish you mentioned. I definitely want to get some fish with some colors that stand out. I'm sure I'll have a couple of clown fish... I just love how they look!

As of right now, I don't plan on adding any corals. I will be going with a T5HO system if I do, though. I have done TONS of research on saltwater aquariums, as they were my main interest when I started to want to get back into fish-keeping.

Thank you for taking the time to post all of those fish. I can't wait to start picking them out!

I live near a place that sells CUC combos where you tell them what size aquarium you have, and they will bundle you up a good CUC for a discounted price. I will consider getting a refractometer. I've got to do some research on them to see what's worth paying for, and what's not.

Thanks again for all of the recommendations and help so far. Very much appreciated!

As for updates on the build, today I plan on building the spray bar and painting it.

What do you guys think, should I paint it black, or blue to match the blue background?

Oh, what do I plan on running in the filter? Well, I have tons of bioballs, filter floss pads, sponges, crushed media rocks, carbon, and ceramic rings. I don't know what variation I'm going to use. Probably just the same thing I have on the freshwater tank. A tray of bioballs, 2 trays of ceramic rings, carbon, filter floss, and a sponge.

I would not use any biological filter media at all if you are already planning to have live rock in this tank. Biological filter media will require a lot of extra maintenance or it will add a lot of nitrates to your set-up. It's extra work you don't need as with enough live rock, you will get all the filtration that you need already.

Carbon or products like chemi pure would be a good addtion to use in the canister to help your set-up

The more live rock, the better your set-up will become. I would suggest 5 to 10 lbs of live rock, and 10 to 20 of dry rock. Basically about 25% live and 75% dry for a total of around 25 to 30 lbs of rock in total

That is also a great way to cycle your tank pretty quick and easy (fishless of course).
